Use 5V power supply (Provided by servo driver).
If the cable is longer than 20m and prevent
encoder from voltage dropping down, it is better
to use multi wires or thick wires for power line
and ground line.

4.6 Anti-jamming Countermeasures of Power Wiring
To suppress interference, please take the following measures:
 Instruction input cable length should be less than 3 meters,and encoder cable should be less
than 20 meters.
 Recommend grounding cable over 2.0 mm²
 Please install a noise filter on the input side of the power cable to prevent radio frequency
interference.
 To avoid electromagnetic interfering, the followingmethods can be used:
